GAS-sTovE.

` p Specification forming part of Letters Patent No. lAll, dated December 12, 1865; antedated November 30, 1865.

To all whom it may concern:

Be it known that I, LUTHER ERVING, of

rooklyn,v in the county of Kings and State ot' New York, have invented a new and Improved Gas-Stove; and I do hereby declare that the j following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being vhadto theaccompanying drawings, forming a part of this specification, in which- Figure l is a side sectional elevation of my invention; Fig. 2, a horizontal section of a portion of the lower` part ot' the same, taken inthe line x x, Fig. l.

lSimilar letters ot' reference indicate correspending parts.

`This invention relates to a new and imf` proved heat-radiating gas-stove; and it consists in the employment or use of a series ot' cylinders, arranged one within the other, so as to form concentric tlues or draft-passages in connection with a gas-burning apparatus, all

constructed substantially as hereinafter set lforth, whereby it is believed that a large, amount of heat will be obtained by amoderate; consumption of gas. A represents the base ofthe stove, provided` with feet a., and having within it a conical draft-tube, B, which extends upward to the titted centrally a cylinder, G, considerably less 1n diameter than F, the lower end of G being ,connected to the lower end of F by an inclined bottom plate, d, as shown in Fig. 1.

H is a cylinder, which is placed between the cylinders F G, concentric therewith. The cyliuders G H are closed at their upper ends;

but the upper part of G is perforated, as shown at c, to form a communication between G and the spacebetween Gand H. The lower end oi' the cylinder H extends down to the inclined bottomplate, d, and is perforated, as shown at f, to form a communication between the space between G and H and the space between H and I". 1 i

The operation is asfollows: 'When the gas is let into the cylinder C itis ignited at the upper surface ot' the upper perforated plate, b, the flame being supplied with air through the draft-tube B and air mingling with the gas by passing into the lower end of C. The drafttube B, in consequence of being ofconical form, causes the air to impinge against the dame, insuring perfect combustion. tom plate, d, forms achamber above the base A, which affords abundant spacefor the consumption of all the gas. The products oi combustion pass up the cylinder G, through the perforationsc-in the upper part of G, down the space between the cylinders G and H, thence through the perforationsfn the lower part of H, and up between the cylinders H and F, and out through the perforated top c.

By this arrangement a sinuous draft is obtained and a portable heat-radiating gas-stove produced, which may be manufactured at a reasonable expense. These cylinders, in connection with the gas-chamber formed by the cylinder C and the draft-tube B, all arranged as shown, comprise a cheap and efficient heatradiating gas-stove.

I claim as new Aand desire ro-secure by Leti ters Patent- The combination of the conical draft-tube B, cylinder C, perforated or reticulated plates b b E, and inclined bottom plate, d, of the concentric cylinders F G H, all the said parts being constructed and arranged to operate as herein specified.
